MULTIGRAPH COMPANY, OF WILIIIINGTON, DELAWARE, A CORPORATION 0F DELA- WARE TYPESETIING MACHINE Application led January 22, 1929. Serial No. 334,200. U

This invention relates to a keyboard operated typesetting machine, and is particularly concerned with such provisions of the mechanism as will enable the rapid assemblage of short grooved type, such as used in the multigraph. Preferably the assemblage is made directly onto a channeled inultigraph segment, Which may thereafter be installed in a multigraph for printing in cooperation with a suitable platen. Positiveness of operation and continuous control of the type from the time it leaves the case until it is mounted in the assemblage member is one of the objects of the invention.

Another object of the invention is to provide for printing a reproduction of the characters as they are being assembled, thus providing at once a guide to the operator and a proof of theassembled matter. In accom- 0 plishing this, I employ both as the printer and the keyboard for the typesetting'machine, a standard typewriter` which is so mounted and connected that its keys may be operated in the usual manner to print on paper on the carriage and atA the same time effect the select-ion of a corresponding type in the case, which is thereupon ejected and is added to a line of characters being formed.

One of the features of my invention comprises arranging the selecting mechanism of the type setter which is operated by the type- Writer in such/.manner that no positive connection of the/'typewriter is required. When the typewriter is put into place, it automatically7 con/tes into position With relation to the selecting mechanism, the keys of the typewriter' operating by a push on the selecting mechanism to effect the conjoint operation; but Whenever desired the typewriter may be simply lifted off for usc elsewhere by simply disconnecting the clamps which engage its frame.

A very valuable feature of my invention is the provision of means absolutely preventing the transposition of characters, no matter how rapid the keyboard may be operated. This is effected by automatically locking the keyboard and type selector against subsequent operation as soon as any key is depressed, and continuing such locking until after the ejected type is actually in the assembled line.

Ease of manual operation of the machine is also one of the features of the invention, and this I effect by constraining the selecting mechanism by power and provide triggers to be released by the typewriter keys, so that hardly any more Work is required of the opcrater than that usual in manipulating the typewriter. Other features of the invention, contributingt'o the eiiciency of the complete operation, will be apparent from the following detailed description of an embodiment of the invention, the essential novel features of which are summarized in the claims.

Briefly, as illustrated in Figs. 1, and 3, my typesetting machine comprises several correlated instrumentalities, to which I have apportioned reference numerals as follows:

1st. A standard typewriter covered by reference numerals 1 to 99, which include also the supporting frame;

2nd. An upright duplex type case having channels apportioned yto the different type characters equipped with ejecting plungers, 100 to 199;

3rd. Normally constrained mechanism released by the keys of the typewriter for selecting the type-ejecting plunger-200 to 299;

4th. Power operated mechanism released by the selecting mechanism for operating the selected plunger to eject type from the bottom of the type case-300 to 399;

5th. Subsequently acting power mechanism for transferring the ejected type to add it to the line being formed-400 to 499;

6th. A multi-channeled type holder `500 to 599 in which successive lines are assembled into a page form suitable for printing;

7th. Certain manual controls-600 up.

The main frame of my complete machine includes a bed plate 1 which is supported on suitable legs 2. The frame 11 of the typewriter which is supported by the bed 1 preferably by means of standards 3 rising from the bed. The typewriter frame may be clamped to the bed bf an suitable typewriter clamp not shown. `he liey lever mechanism of the typewriter, however, simply has a push connection with the typesetter mechanism, enabling the typewriter to be readily lifted off when its frame is released.

The typewriter machine ma suitable form, preferably one ofy the existing standard machines, and, as shown, comprises the frame 11, paper carriage 12, platen roller 13 carried thereby, finger keys 14, key levers 15, type bars 16 operated by the key levers t0 print on paper against the platen. Each type bar has upper and lower case characters 17 and 18, selected by movement of the carriage by a shift key as later explained. The inking ribbon of the typewriter and various other parts are omitted from the drawings, as they will be well understood.

' Thel type case in which the 'type is stored, comprises a series ofparallel upright rails 101 and 102 with overhanging edges and suitable cross members 103 and 104 near the top of the rails, and 105 and 106 near the bottom thereof, secured to the backs of the rails. These rails are preferably I-shaped in cross section, as illustrated in Fig. 27, and they /occupy grooves in the cross plates, the base flange o the rails seating in such grooves, and the metal of the plate being peened over the rail base. I thus provide a pair of rigidl multi-channeled upright members having their channels undercut, whereby they are adapted to confine type grooved on its opposlte sides, such type being of the character illustrated at A, Figs. 22 to 27 inclusive.

be of any The cross bars 105 and 106 to which the vertical rails of the type case are secured extend crosswise ofthe machine and are secured at their ends to angle brackets 107 which in turn are secured to vertical plates 108 and 109 which are secured to the frame plate. The vertical plates also carry the cross bar 110 which forms the base f'for the channels, the support for the plungers, and provides the intermediate ledge or runway 111' onto which the type are ejected. j

One ofthe type banks for instance the forward bank 101 is designed to carry lower case type and lthe other bank (102) carry the corresponding type of the upper case.v The type in both banks face forwardly. The type descend by gravity to the lower end of their cases from which the bottommost type of the channel may be ejected by mechanism released by thecorresponding key in the type- Writer. The type is ejected from the front bank 101 rearwardly and from the rear bank 102 forwardly, so that in either case they come onto the intermediate ledge. As the typewriter is provided with a shift key, enabling each key lever to print either of two characters, I provide shift mechanism for the type case, coupled with the typewriter shift key, whereby lower case characters on the typewriter serve to eject lower case characters on the type case, for example. This will be hereinafter explained.

Extending through the bottoms of the respective type cases, are plungers 120 and 121, one for each type channel, each plunger occupying a groove in the base bar 110. Plates 112 extending across the grooves outside of the type case proper, complete the guides for tlie plungers. Y

Each plunger 120 or 121 is engaged by a corresponding bell crank 122 or 123, the upper ends of which enter notches on the undersides'of the plungers, while the'lower arms of the bell cranks furnishmeans by which they are Operated as later explained.

The corresponding front and back bell cranks are constrained toward each other by a light tension spring 125, which tends to keep the plungers in their innermost positions. Standin in registration with the outer ends of the pingers, are a pair of universal cross rods 130 and 131, inounted on spring arms 132 or 133, leading from rock shaft-s 134 or 135. When the machine is idle, the' cross rods 130 and 131 bear against the outer ends of all the plungers, but, when any bellcrank isoperated to withdraw the plunger, that action carriesback thecorresponding cross rods.

As soon as a plunger is withdrawn, the bottommost type yin the channel` which was resting on top of the plunger, will now drop in front of it. The side ribs of the rails of the type case terminate a distance above the plate 110 somewhat greater than the thickness of a type, so that when a type dropsin front of a plunger, it is released from the,

rails which had occupied its grooves; also the webs of the base bar 110, whichv stand between the plungers, terminate short of the type case rails, so that the type in front of the withdrawn plunger isy free from lateral confinement. Thereafter suitable mechanism, to be described, rocks the shaft 134 or 135, forcing the withdrawn plunger into the type case and ejecting'the bottoinmost type intothe intermediate runway 111 between the cases.

I will now describe the mechanism by vwhich the depression of a finger key of the typewriter operates to rock the corresponding bell crank 122 or 123, to withdraw a plunger, and also initiates the mechanism to operate the i this lever and` havin 203, rising from a frame plate 1 of themachine, AY0

A suitable upward extension 205 secured to a shoulder directly under the key lever an close to it, causes the depression of the lever 201 whenever the key lever is depressed. A tension spring 206, acting on the rear end of each lever 201, tends to elevate the forward end. The typewriter machine is customarily provided with springs 20 (Fig. 3) acting upwardly on each key lever, and adjusted by screws 21. These springs are preferably left in the machine, so that the'springs 206 need be no stronger than suiicient to raise the levers 201, against a v suitable stopping cross bar 208.

On each lever 201 is a dog 210 pivoted to the lever at 211 and'normally held in the vertcal position shown, as a spring 213 pressing a pin 214 on the dog against the underside of the lever-201. This dog normally overlies a pivoted latching trigger 22,0- on a lever 230, which is pivoted at 231 to a frame standard 232, and extends well to the rear of that pivot into position to operate the bell cranks 122 vand 123. Suitable tension springs 234 of considerable force connected to the rear portioni of the lever, tends to elevate that portion and lower the forward portion. Such lowering is prevented by the latch 220 engaging an abutment bar 222, 'a suitable sprin 223 between the latch and lever 230 norma ly maintaining the latch in the position shown in Fig. 3. The latch 220, it will be understood, is an L-shaped or U-shaped piece of sheet metal, embracing the lever 230 and pivoted by the pin 225.

Now, when the key lever 15 of Fig. 3'is moved downwardly, lever 201 must move downwardly, thus causing the dog 210 to press downwardly on the trigger 220. This movement swings the trig er on its pivot 225 sutiiciently to release it` rom the abutment bar 222, whereupon the spring 234 swin the lever 230 into the position shown in ig. 4.

Each lever 230 extends beneath a corresponding pin 240, the set of pins being slidably mounted in an oscillatable yoke 241. If this yoke is in the position shown in Fig. 3. the pins will stand beneath the forward set of bell cranks v122, and hence elevation of the rear end of the lever 230, consequent upon the actuation of the trigger by the depression'of the typewriter key, will swing upwardly the horizontal arm'of the corresponding crank 122, thus withdrawing the plunger 120. If, however, the yoke occupied a rearward position, as shown in Fig. 5, the vmovement of the same key1v would shove upwardly on the hori- Zontakarm of the bell crank 123, thus withdrawing the plunger 121. The yoke 241 is connected with thc'sliiftkey of the typewriter. 133

Normally, the typewriter is operating with the lower case characters 18 on the type bars 16 and the yoke holds the pin 240, operating on the forward bell cranks 120 which are associated with the lower case type case 101. lfVhen the typewriter shift brings the characters 17 into use, the yoke 241 is automatically shifted to bring the rear type case 102 into action.

The shift connection is best shown in Figs. 8 and 9. The yoke 241 is in the form of a bale pivoted at its ends 242 to the upright plates 108 and 109 at opposite ends of the type case. Secured to the bale is a link 245 leading forwardly to a bell crank 246 which has a lip 247 extending beneath the shift lever 30 of the typewriter. As shown in Fi gs. 8 and 9, this shift lever is pivoted at 31 and has an upwardly extending arm 32 operating on a member 33 in the nature of a bell crank rigid with a cross rod 34 on which rides a roller 35 carried by the typewriter carriage 12.

The usual position of the shift mechanism is that shown in Fig. 8, where the lower case characters 18 of the typewriter are in position to coact with the platen roller 13, and the pin yoke 241 is in the forward position. Now, when the shift key is depressed, its lever is rocked into the position shown in F ig. 9, which, through the mechanism stated, raises 'the typewriter carriage to bring the paper rolled into position to coaet with upper case characters 17, and at the same time rocks the pin frame 241 into the rear position, as shown also in Figs. 4 and 5.

It will be understood of course, that the particular shift mechanism on the typewriter will vary with the make of typewriter employed, but for such shift mechanism to operate the setting machine, it is only necessary to arrange the bell crank 246 or its equivalent so that it will be engaged and operated by some movable part of the typewriter shift.

I provide mechanism preventing the depression of two keys at the same time. Such mechanism may readily comprise the well known expedient of a row of balls extending transversely across a set. of levers in position so that any actuated lever must pass between an adjacent pair of balls, and there being only space enough in the whole train of balls `for one lever. This is illustrated in Figs. 2, 3 and 35. As there shown. 200`1`ndicatcs the balls and 261, 202 a container therefor shown as comprising a grooved overhanging bar and a. retaining plate. The plate and bar are slotted in their upper portions for the passage of each key lever. Suitable abutment screws 205 at the ends of the ball raceway adjust their position.

The device just described is shown as carried by the frame 1, through suitable brackets, and as located directly beneath the forward ends of the levers 201. Vhen any such lever is depressed, as indicated in one instance in Fig. 35, the aggregate space between the balls` is appropriated so that no other lever may be depressed until such depressed lever has been returned. This effectively prevents the ejection of two type at a time; it also revents'jamming of the typewriter type ars, by preventing two keys being depressed at once. Other mechanism hereinafter described operates automatically to lock the keyboard against actuation of a subsequent key immediately after a key has been depressed. This automatic locking takes effect substantially concurrently with the return of the key-operating lever from the train of balls, so that it is not within the manual capacities of the operator, in any normal operation of the machine, to depress a second key until after the machine has completed the operation initiated by the first key.

It will be understood from the description so far given, that whenever a key of the typewriter is depressed, it prints on paper on the `carriage in the usual manner, and it also opcrates to the corresponding trigger to cause the withdrawal of the plunger from the corresponding type channel, ,and the moving back of the corresponding universal plunger operating bar. The additional manual work for the operator in releasing the triggers is insignificant, and such operation throws into action suitable power mechanism which completes the ejection and transfer of the type without requiring further work of the operator. Mechanism for accomplishing this will now be described.

In the particular embodiment illustrated the power for the machine is derived from an electric motor 300 (Fig. 2) the armature shaft 301 of which carries a pulley 302 connected by a belt 303 with a pulley 304 which cor-stitutes the loose member of a single rotation clutch' mounted on the shaft 310. Secured to the underside ofthe bed plate 1 of the machine are a pair of depending plates 311 and 312 (Fig. 12) suitably bracketed at their lower ends by a cross-rod 314. The shaft 310 is mounted in these vertical plates, and the clutch mechanism is mounted on the shaft between the plates.

The clutch is released by the action of any of the levers 230 which operate to raisea vuniversal bar 250 extending across all of the levers. The releasing of the clutch givesa single rota-tion to the shaft 310 which, as presently explained, operates the rock shafts 134 and 135 to force inward any withdrawn plunger at the bottom of the type case, ejecting the bottommost type.

I will now describe the clutch and its immediately coacting` parts as illustrated in Figs. 3 and 10 to 16 inclusive. This mechanism includes a driving member 304 which is a pulley loose on the shaft and carries an annular flange 305, which is shown asmade sepers 330 between the driving and driven mem! ber, and a retainer ring 331 positioning the rollers equi-distantly. The retainer 331 comprises a plate journalled on a reduced portion of driven collar 320 and having an interrupte annular portion 332 which projects between successive rollers 330. The plate 331 is held in place against displacement by a plate 335 mounted on a hub portion 336 of the collar 320. s

The plate 331 is provided witha radial shoulder 333 which rests normally on an abutment 340 controlled by the universal bar 250. A suitable tension spring 338 connects the plates 331 and 335 and is normally constrained when the shoulder 333 engages the abutment, which is the position illustrated in Fig. 15. This maintains the rollers on the concentric portions of the collar 320, so that the latter is not driven.

lVhen the abutment is removed from the shoulder 333, the spring 338 reacts and shifts the disk 331 circumferentially with reference to the collar 320 and thus carries the rollers 3() onto the tangential portions of the collar, binding the collar to the driving pulley 304 and giving a rotation to the shaft 310. During that rotation, the abutment 340 will have been returned to normal position so that at the conclusion of the rotation the disk shoulder 330 will engage the abutment and stop the movement of the shaft at the end of al complete rotation. y

Keyed on the shaft 310 is a cam member 350. This member has two disk cams nearly 'l but not quite alike; that is to say, there 1s a.

cam 351 which is circular for over .threequarters of a circumference and then 1s Hattened by a chord 352. The ther cam 353 1s circular for a slightly gr ter arcuate distance and is flattened by apartial chord 354 similarly placed to the chord 352, but connected at one end to the arc by a cusp 355. These cams rotate in the direction of the arrows in Figs. 10 and 11.,'and the cam 353 releases its roller slightly later in the movement than the cam 351.,"

The cam/353 coacts with a roller 360 on a lever 36]."which is pivoted by a stud 363 to the depending frame plate 311. Beyond its pivot/the lever is connected by a link 365 with one/of the bale arms 251 of the universal b i' 250.

' Normally', the flattened portions of the cams 351 and 353 stand adjacent the cooperating rollers as illustrated in Figs. 10

and 11. In this position, the depression of any typewriter key results in rocking the down in the recess of the cam 351 vwhile the abutment 340 withdraws from the clutch shoulder 333 and the clutch is released. As the shaft 310 now rotates, the cam member 350 turns in the direction ofthe arrow. This raises the roller 360 as the concentric portion of the cam comes beneath it. This rocks the abutment 340 back into potential position. 1t also pulls down the universal bar 250. This operates to restore the actuated lever 230. After such restoration is completed, the latch 220 is swung by its spring 223 to bring its footionto the seat provided by the recessed edge of the bar 222, re-locking the lever.

, The arms 251 of the universal bar 250 are rock arms on a rock shaft 370 (Figs. 21 and 31). On this rock shaft is an arm 371 carrying at its free end aepin 372. This pin extends into forks at the opposite ends of the rock arms 375 and 374 which are rigid on the rock shafts 134 and 135 which carry respectively the universal pusher bars 130 and 131.

Y It results from the above described mechanism that whenever the concentric portion of the cam 353 engages the roller 360, the universal pusher bars 13() and 131 are moved toward each otherby power, and hence any withdrawn plunger 120 or 121 is shoved inwardly to leject the bottommost type onto the zone between the twotype cases on the surface of the cross bar 110. Mechanism to be shortly described then acts to advance the ejected type toward the right hand end of the machine, where the type are assembled into a line ready for delivery onto the multigraph I segment.

The action of carrying the ejected type along the runway 111 is effected by the cam 351, the operation of which will now be described. This cam acts against a roller 38() on a lever 381 pivoted at 382, (Fig. This lever carries at its free end a pin 383 engaging a slot in a lever 384 pivoted at 385. The roller 380 may be given a tendency to move toward the cam by a suitable spring 386 an chored to either lever 381 or the lever 384.

The lever 384 performs several functions simultaneously. One of the most important is to lock all the latches 220 on the levers 230 so that the typewriter vcannot be again operated until the type setting operation initiated thereby is completed. This prevents the possibility of transposing type by operating the keys in very rapid succession. This locking mechanism is best shown in Figs. 3, 4, 5 and 10 and will now be described. To prevent the depression of a key lever of the typewriter during the cycle of movement of the clutch controlled cam, I provide a lock 390 which consists of a rocking plate projecting in the vicinity of the heels ofthe latch 220 operated by a rock arm 391. This arm is connected by a link 392 to the upper arm 393 of a bell crank which is pivoted to the frame at 394 and has a lower arm 395 connected by a link 396 with the lever 384 above referred to. The result is, that whenever the cam 351 has its concentric surface against the roller 380, the plate 390 is automatically swung upwardly behind the heels of all of the latches 220 as illustrated in Fig. 5, thus locking the latches and preventing operation of any key lever of the typewriter.

I have found that a convenient speed of rotation of the clutch is 350 revolutions per minute, and at such speed the cam moves the bar 390 to locking position in such a small,

fraction of a second, that it is physically impossible for the operator to depress a key in the minute theoretic interval between the release of the keys by the ball-lock and the locking by the bar. j

The second operation erformed by the lever 384, when actuated y the cam 351, is to lock down the universal bar 250. This is effected by the universal bar being engaged by the hooked upper end 387 of a downwardly drawn link 386 connected to the lever 384.

A third operation of the lever 384 as actuated by the cam 351 is to operate mechanism shoving downwardly on any type arriving at the end of the horizontal runway 111. This is accomplished through a link connected to the free end of the lever 384, but the explanation will be deferred until after the transfer of the type has been described.

Another o eration performed by the single rotation sha t 310 is to shove the ejected type along the pathway 111 between the type cases.

This is effected by a crank 410, Figs. 3, 10 and 12, on the shaft 310 which has a pin 411 pivoted in a block 412 slidable in a slot 413 in an arm 414. This arm has a slidable pivot below the crank pin by means of a second slot 415 in the arm embracing a fulcrum pin 417.

The fulcrum pin 417 is fixed in use but adjustably positioned. To this end I make this pin a crank pin on the end of a crank 416 pivotally mounted on a stud 419, and I provide suitable means for locking this crank in adjusted position. A convenient device consists of a pair of set screws 418, Fig. 30, mounted in ears carried by the plate 312 and engaging opposite sides of the crank near the pin 417. y

The upper end of the arm 414 carries a roller 420 (Figs. 10 and 12) which operates in a horizontal groove 421 in a stationary bar 422 supported on posts 423 and 424 rising from the bed plate 1. The roller 421 is journalled on a screw 430 mounted in the arm 414. On the other side of the arm a bushing 431 is mounted on this screw. This bushing is pivotally connected with a block 435 which carries a horizontal bar 440 in line with the runway between the type cases just above the floor 110 therefor.

It results from the above construction that case a type should for any reason foul, I connect the arm 414 with the block 435 in such manner that it is readily detachable therefrom. As shown in Fig 10, the bushing 431 occupies an open notch 436 in the block 435, which notch is in effect normally closed by a plunger '437 pressed upwardly by a sprin 438 mounted 'between ears on the block rdinarily, the connection acts as a usual pivot, the pin rocking in its bearing, but in case there is any obstruction to the movement of the transfer bar 440, the pin 431 will simply pull out of the slot 436, camming down the plunger 437 in such movement.

Vhen a type has been ejected, either rearwardly from the front bank of type cases, or forwardly from the rear bank of type cases, it lies on its side on the support provided by the cross bar 110. Now, the clutch operated mechanism through the crank 410 and/.oscillating lever 414 just describe-d operates to advance the push bar 440 along this path. The forward end of this bar engages the ejected type and shoves it along the runway to a point adjacent the' right hand side of the type cases.

The channel 111 along which the bar 440 shove the type A terminates at its right hand end in a vertical channel 470 which curves downwardly in a quadrant form. This channel is made to t the contour of the type sufficiently to guide it but loosely enough to allow it to drop freely, thus on opposite sides of the channel are curved ribs 471 and 472 (Figs. 17 and 26). The members supporting these ribs are cut away in front thereof to form rabbets for receiving the head of the type and are cut away to a somewhat less eX- tent to the rear to form rabbets to receive the feet of the type. Accordingly, as the plunger 440 is operated to its eXtreme right hand position, the type A is shoved off of its support, and thence drops downward by gravity onto the curved chute, the rib 471 engaging one of the grooves of the type and the rib 472 the other groove.

As the type are very light, they are liable to become displaced, and I therefore provide means to true them up and control the transfer along the horizontal channel to the down-
